An eco-friendly wetsuit jacket made with sustainable Yulex: neoprene free and Fair Trade Certified sewn. Wear it alone for added warmth when there's a chill to avoid or as protection from the suns rays. The men's Patagonia R1 Lite Yulex 1.5mm Front Zip Long Sleeve Jacket can be worn alone or layered over a rashguard. Fit should be snug to prevent flushing when you hit the water.

Patagonia has reformulated the Yulex material in their spring suits, making them lighter, stretchier and more comfortable. Made of 85% natural rubber/15% synthetic rubber by polymer content that replaces a petroleum-based material with a plant-based one, they offer the same performance attributes as conventional stretch neoprene while reducing CO2 emissions by up to ~80% in the manufacturing process. Derived from sources that are Forest Stewardship Council certified by the Rainforest Alliance, natural rubber has been blended with chlorine-free synthetic rubber to increase ozone- and UV-resistance and meets very rigorous standards for strength and durability. Offering full-arm warmth, comfort, and sun protection, the redesigned, neoprene-free R1 Lite Yulex Front-Zip Long-Sleeved Top is 1.5mm thick, with a stretchy and fast-drying 100% recycled polyester interior lining; the exterior face fabric is made of durable, water-resistant 88% recycled polyester/12% spandex. The face fabric and lining are now solution dyed—using 86% less water than conventional dyeing—and are laminated with water-based AquaA glue that’s free from harmful volatile organic compounds (VOCs). A streamlined anatomical design holds close to the body for maximum flex, and other features include a vertical front-zip entry with corrosion-proof Salmi zipper and a low-profile, fused-edge hem at the waist. For additional strength, seams are triple glued and blindstitched and are internally spot taped at high-stress areas. Made in a Fair Trade Certified facility. Suggested water temperatures: 65–75° F/18–23° C.
